Most of the attention in this category goes on the price you pay to start. The more useful question, and the one almost nobody asks first, is what happens when you want to stop.
80 of the 166 sellers we review say something about canceling, refunds or commitment. What they say varies more than the prices do.
The discount and the exit are the same number
This is the thing worth internalizing. A seller offering $249 monthly and $124.50 on a twelve-month plan is not running two prices. It is charging you half as much for giving up the ability to leave. The saving IS the lock-in, priced.
That is a fair trade if you know you will continue, and a bad one if you are trying it. And trying it is what most people are doing, because the evidence for injected NAD⁺ does not tell you whether it will do anything for you. A category with uncertain benefit is exactly where a year of commitment is hardest to justify.
What a genuinely easy exit looks like
A handful say it plainly. One states no contracts, no cancellation fees and no membership fee — and adds the detail that decides it in practice: your current month’s shipment goes out before a cancellation takes effect. That last clause is the one to look for, because it is the difference between stopping now and stopping after one more charge.
Another bills every 28 days with no long-term commitment. A third labels its plan “pay monthly, cancel anytime”. None of these is remarkable and that is the point — the ones who make it simple tend to say so in one sentence.
The good idea almost nobody copies
4 sellers state that you are not charged unless a provider approves you. One checks you out first and takes payment only after a doctor signs off. Another promotes “only pay if prescribed” on the page itself.
Separately, 7 promise a full refund if the prescription is not approved — one charges $5 for the visit and refunds it if a physician decides you are not a candidate.
Both arrangements remove the same risk: paying for something a clinician then declines to prescribe. It costs a seller almost nothing, since they were never going to keep that money, and it is worth noticing which ones bothered to say it.
Five questions before you start
- Is this a rolling month or a term? If a term, how many months?
- Does it auto-renew, and at what price?
- If I cancel, does the next shipment still go out and get charged?
- Is there a fee to cancel, and is there anything to return?
- If the provider declines to prescribe, do I get my money back — and does that include any consultation fee?
A seller who answers all five in public has told you what you are signing. Most do not, and that is information too: the scorecard counts what each one publishes across four other questions and the pattern is similar.
One thing the cheap monthly price hides
Watch the billing cycle as well as the term. A plan billed every four weeks charges you thirteen times a year rather than twelve, so a $229 “monthly” plan is $2,977 a year and not $2,748. The annual-cost tool does that arithmetic, and the advertised figure is often not the standing one either — two separate things to check before you agree to twelve of anything.
